摘要
在马尾松造林地上开展不同整地方式的试验研究 ,结果表明 :不同整地方式在造林初期对土壤物理性质产生影响 ,表现为全垦改善土壤物理性质效果最好 ,带垦次之 ,穴垦最差 ,而土壤化学性质差别不明显。造林 5年后 ,整地方式对土壤理化性质影响表现为穴垦 >带垦 >全垦 ,而林分生长状况则表现出全垦 >带垦 >穴垦的趋势 ,这种生长差异随着林木年龄增长将减少乃至消失。
The experiment of site preparation modes was carried out in the forest soil of Pinus massoniana. The results indicated that site preparation modes affected the soil physical properties and showed an improvement action on soil physical properties as whole reclamation>band reclamation>hole reclamation. The difference in soil chemical characters was not significant. The effects of site preparation modes on soil physical and chemical characters showed as hole reclamation>band reclamation>whole reclamation after five years of planting. The stand growth showed the tendency of whole reclamation>band reclamation>hole reclamation. However, the difference in the growth would gradually reduce and disappear at last with the stand aging.
